1 A v 'WOW COOLING- AgND WASHING APARATUS.

Moenia,

To allwhomtm'yo'ncem:

Be it known that we, OSCAR .W. HAGBERG and EMIL M. LINDE, subjects of Sweden and r the United States, respectively', residing at 5 the city4 and county of San Francisco and State of alifornia, have invented a certain new and useful improvement infWindoW Cooling and Washing Apparatus, of which tle following is a speclfication. l l The present invention relates to an attachment for windows particularly those of meat markets, fruit and vegetable stores` or any other establishment wherein it \is de sired to maintainthe'interior'of the store cool, the 'window clean, and to prevent the accumulation thereon of steam, frost ,or ice.

By our present apparatus, a thin volume of water is uniformly distributed over the upper edge of a window passing by gravity in afree lthin sheet downwardly of theN inner window surface affording afree rapid evaporation which-will maintain the temperature ofthe room at a relativelylow degree.

Our present invention-will by its use lendisplay in the window of perish- H able articles for a considerably longer period than ispossible under ordinarynonrefrigerating' conditions, 'and .duev to the novelty of the water sheet iiowi-n on the window will attract the attention o? passersby and serve as an advertising medium.

Theinvention consists mainly in the provision of means associated with a distributor head for causing the water to flow downwardly of the window in a solid sheet, and at the same time to 'provide an apparatus which is capable of being readily positioned in co-operative relation with display win-Y dows in general, and which is adapted for 40 ready removal at little expense.,

A With the above mentioned vand other objects in view, the invention consists in the novel construction and combination of-v parts hereinafter described, illustrated in the aci companying drawings, and setforth in the claims hereto appended, it being understood that various changes in the form, proportion, sizey and minor details of construction within ,thelscope ofthe claims may be resorted to without departing from the spirit A or sacricing any of the advantages of the 6 invention.

To more fully comprehend the invention, reference is directed to the 'accompanying drawings, wherein y Figure 1 is a view in elevation of a win- Specication of Letters Patent.

therewith.

Figure 2 is a vertical sectional view taken online 2 2 of Figure 1 through the di"s tributor head, distributor screen and distributor pipe.

Figure 3 is a sectional View taken on line 3 3 of Figure 1 disclosing more clearly one of the clamping members. p v65 Figure 4 is a view in broken elevation Y illustrating a portion of the distributor head, distributor pipe, and distributor screen.

Figure 5 is a sectional view taken on line 5-5 of Figure 1 disclosing the gutter andI waste pipe.'

Referring more particularly to the several views of the drawings wherein like characters of reference designate corresponding parts, 1 isla sash or frame mounting the '75 glass 2, and extending vertically of one side of the sash or frame 1 is a water feed pipe 3, the supply to which is controlled by a valve 4. The pipe 3 is bent at right angles at its upper end and extends longitudinally of the upper wall of the sash or frame 1 l as at 5, to approximately the horizontal cen r thereof, where it connects with one end of a flexible coupling or hose 6. Extending transversely across the bottom of the sash or frame -1 is a gutter 7 for receiving the water passing down the window 2, and the water drains 'l from the gutter through a waste pipe 8. f Disposed transversely of the upper edge of the window `2 is an elongated distributingi head 9 substantially triangular in cross section closed `at its opposite ends and open for the full area of one face as at 10, the opening being disposed facing the window 2 as irr Figuresl 2v and 3 of the drawings. Within the head 9 is fixed`a distributor pipey e 11 extending longitudinally thereof and formed within 4its center with an inlet 12 connected with the feed pipe 3 through the flexible coupling 6. The distributor pipe 11 is perforated as at 1? throughout its length, the perforations being disposed to direct the stream flow issuing therefrom outwardly and downwardly relativelyfto the opening 10. `fll`o obtain a vuniform distribution of the water pver the entire upper surface ofthe window 2, to insure a complete covering of the inner surface of the window wardly thereover, we interpose betweenthe distributor head 9 and the glass or window@ a distributor screen 14, preferably of metal,

50 i thereof' against the screenlt to tlghtly reand the lower edge of the-screen is bent or v folded rearwardly on itself, as at 14, to provide a portion of double thickness on which the lower edge 15 of the distributor -head 9 flo rests, as in Figures 2 and 3 df the drawings. The longitudinal terminal edgeseof the screen 14; are reinforced by the reinforcing rods 16 around which the screen is bent, and the rod associated with the lower edge is adapted to lie within thedistributor head, and the rod associated with the upper edge is adapted to lie exteriorlyand longitudinallyn of the upper edge 17 of said distributor head for the'hereinafter vdescribed purpose. 'l

It will be apparent thatthe screen coveringon the distributor head-which affords y a great number of very small outlets between the lower ed-ge l15- of the head 9 and the window 2, insures the water streamleaving the interior of the distributor head in a thm sheet, and it will be understood that by the use of ,this distributor screen, the surface of the lwindow 2 throughout the entire j screw 21.

len h of the distributor head is moistened, an through capillary attraction, the water passes from the folded edge 18 of the screen in a solid' sheet instead of in numerous small streams, which may or may n'ot converge after striking the window to pour a solid sheet. f e

To detachably secure the distributor head .to` the window or glass 2, we mount on the 'upper' member of thesash or frame 1, spring brackets 19, bent as at 20 to. overliev the head andeach carrying a .tension screw 21 which screws are disposed 1n a plane below `the longitudinally raised edge 22 of the head 9.

To .force the head 9 u wardly againstY the rod 16, and to in turn orce the rod into contact with the shoulder 23, a1

suitable head engaging c lip 24 rests on the edge 22 with one wall or surface extending a short distance over Vthe'lower surface of the head 9, which surface is cupped' as at 25 to receive the lower end of the tension f It will be observed that the the tension screw 21 will direct its force mainly on the lower side of the distributor head 9, and while it will force the edges tain the same against the inner surface `of the glass or window 2, a lateral pressure `is also exerted on the head 9 to force the same upwardly in contact with the shoulder 23.

We claim :f- 1. The combination of a frame having a `glass fitted therein, a' distributing head ex? -tending transversely of the upper edge thereof, said head having an- 'open side v v disposed toward the glass, a1 distributing screen over the open side of the head 1n adjustment of contact with thel glass and 0n which the edges of the open side of the headre'st, a perforated distributing 1pipe disposed longitudinally within the head with its inlet extended rearwardly throughsaid head, a

watei` supply pipe connected therewith, and ayclamp carried by the frame and bearing on the head for' detachably retaining the screen in tight contact with the glass.

\2. The cmbination of a frame having a glass fitted therein, a distributing. head extending transversely. of the upper, edge thereof, said head having an openside disposed 1n close roximity'V to the glass, a

fabric positione Abetween the lower edge j of the head openingn and the glass and on which said edge bears, a perforated distributing pipe carried by and extending longitudinally within the head with its inlet extended rearwardly through said head, a water supply pipe detachably connected therewith, and a spring clamp carried by the frame and overlylng said head and adapted to engage the head to detachably of one face affording a water outlet adjacent to the glass, a perforated distributing pipe disposed longitudinally within the head with its inlet extending rearwardly therefrom and with the perforations disposed toward theilower edge ofsaid opening, a distributing screen positioned in contact with( the glass and over said distributing head fopening with vthe edges' of said head opening lresting thereon, a reinforcing rod carried .by the upper and lower edges of said screen, `.the lower edgevofsaid screen being bent or folded rearwardly to provide a double thickness at the lower outlet edge of said distributing head, a water supply pipe coni nected with the distributing pipe, andA means coacting withthe head for detachably retaining the same in position' against the screen and the screen against the glass.

ln testimony whereof we have signed our names to this specification.
